 Trustindex verifies that the original source of the review is Google. I found Warren and his team to be very professional. They gave reasonable deadlines, and were helpful when looking to 'problem solve'. I wanted a top quality loft conversion, which is exactly what I ended up with. Would not hesitate to recommend them, and will hopefully use them again for other projects. Emphasis on customer satisfaction and communication throughout the project.

 Trustindex verifies that the original source of the review is Google. We’ve used WJ Construction twice, the first time for a kitchen renovation that also involved a general rewire and the removal of a waste access point. It was a reasonably complicated job, made more so by the fact that we had it done in 2020. Warren and the team were brilliant: thorough and professional, flexible and problem-solving. Good communication throughout too. That’s why we were very happy to have them back two years later for a loft conversion and bathroom renovation. Again, great work all round. No hesitation in recommending them.

 Trustindex verifies that the original source of the review is Google. Warren and his team spent the summer months of 2024 carrying out a significant update to my property, consisting of a new roof, bathroom, rear extension and patio. I would have no hesitation in recommending Warren and the team to deliver your project. Warren was always very attentive to our requirements and assisted greatly in ensuring that everything happened in the right sequence. 10/10.

 Trustindex verifies that the original source of the review is Google. The guys did just the structural elements for my terraced loft conversion in East London. I have no complaints at all. They were the only ones that actually shared all their insurance and creds without prompting when quoting. Had all their own teams etc and sign off for electrics not a prob or anything like that. Very communicative on whatsapp, decent pricing comparative to the market. Also recommended them to a friend for a loft conversion to completion and they had a great experience too.
